This paper describes the properties of proprioceptive sensations induced by an asymmetric vibration using a vibration speaker-type non-grounded haptic interface. We confirm that the vibration speaker generates a perceived force that pulls or pushes a user's hand in a particular direction when an asymmetric amplitude sound signal that is generated by inverting a part of a sine wave is input. We conducted 5 psychophysical experiments and evaluated the subjects' physical properties in order to apply this phenomenon for a variety of applications. As a result, we confirmed that the vibration speaker was able to control both the direction and magnitude of the reaction force by changing the input signal.

The "SpinDome" is an image display using wide-angle spherical screen. Sphere is an ideal shape of a screen that covers human visual field. The optical system of the SpinDome employs two mirrors: a flat mirror and a spherical convex mirror. The flat mirror bends the light so that the viewer can see the image from the center of the spherical screen. This optical configuration enables seamless wide-angle image in a very limited space. A rotary mechanical shutter is set in front of the projectors, which provides stereoscopic image. Effectiveness of the display is exemplified by maneuvering a remote vehicle.

球面没入型ディスプレイで実画像を呈示するには従来のNTSCベースでは解像度の低さが問題であった。本研究ではHDTVを用いることで有効垂直走査線の数を243本から756本に増加させ解像度の向上を図った。またHDTVの画像アスペクト比16:9も原画上の画素利用率に有利に働くことを確認した。これらにより、水平、垂直ともに約3倍の解像度を得られることになる。シミュレーションに基づきプロトタイプを製作し評価を行った結果,従来よりも高い解像度を得た。

In this article, we discuss the artwork about the device which has a furniture appearance and physical input and output functions. Since the chairs has most direct and frequent interaction “sitting” with the users in their daily life, we decided to shape a new interaction between them by making the furniture-shaped device “Escaping Chair”, which has a box stool appearance and interacts with the bystanders by trying to move away from nearby people. By doing this, the device tries to make a person unable to sit on it, stimulating their perception toward their sitting action, while also making the person consider the Chair’s “personality.” We exhibited the chair and collected feedback via conversation and observation. During exhibition, it succeeded in making subjects perceive their own movements and to feel a semblance of will in the chair during their interactions, as we planned, and even making them think alive. Also, they found its playfulness, which indicates a new capability of the device. Exhibition also raised further challenges to explore user interaction.

This paper discusses a new concept named"device art."The recent decades has shown significant advance in the interactive artwork created in Japan.Those artworks employ innovative interface devices. Device art has different characteristics from western art; bottom-up creation process, playfulness, and commercialization. Traditional Japanese culture, such as tea ceremony or flower arrangement, uses sophisticated devices, which are roots of device art. This paper describes characteristics of device art as well as its methodologies for creation of works.

This paper presents a system that consists of three robots to imitate the motion of top volleyball blockers. In a volleyball match, in order to score by spiking, it is essential to improve the hitting percentage of each spiker. To increase the hitting percentage, iterative spiking training with actual blockers is required. Therefore, in this study, a block machine system was developed that can be continuously used in an actual practice field to improve attack practice. This robot performs high speed movement on 9 m rails that are arranged in parallel with the volleyball net. In addition, an application with a graphical user interface to enable a coach to manipulate these robots was developed. It enables the coach to control block motions and change the parameters such as the robots' positions and operation timing. Through practical use in the practice field, the effectiveness of this system was confirmed. In this paper, we describe the effectiveness to players through utilization of the system in actual practice. In addition, we clarify the improvement points exposed at that time, propose and construct a sensor system and describe its evaluation and future possibilities.

The “Big Robot” has two legs with wheels, mounting the pilot at 5m height position. The robot goes forward according with the motion of the feet of the pilot. It is programed to make trajectory of head position of 5m giant. Thus, the pilot feels as if his/her body were extended to 5m giant. The biggest technical issue in large-scale robot is falling down to the ground. Thus, the base frame of BigRobot is made of steel and its linkages are made of CFRP. This structure enables low center of gravity and prevents from falling down. The Big Robot was exhibited at Ars Electronica Festival 2015, Tsukuba Media Art Festival 2015 and Emerging Technologies of SIGGRAPH 2016, that proved its effectiveness.

We here propose a device that can display a translational force and torque using two vibration speakers. Each vibration speaker generates an asymmetric vibration when a sound with an asymmetric amplitude is input. Asymmetric vibrations induce perceived forces that pull or push a user's hand in a particular direction. The user perceives a translational force and/or torque with his/her thumb and index finger based on the direction and amplitude of each speaker's force. We conducted four evaluation experiments to evaluate the mechanical properties and the proprioceptive sensations. As result, we confirmed that the proposed device can present the translational force with a maximum value of 0.5 N and the torque with a maximum value of 9.5 N·mm.

This paper describes development of a food simulator. A taste of food arises from mixture of auditory, chemical, and force sensation. This food simulator is a haptic interface that can generate a force to user's teeth when the user bites a food. It consists of a film-like force sensor and one degree-of-freedom manipulator. The food simulator generates a food texture according to the force profile captured from a user's biting force of a real food. Then the profile of the biting force is replayed by controlling the reaction force of the device.

We developed a spherical immersive projection display, a new model of EV(EnspheredVision). This display consists of spherical screen, plane mirror, convex mirror, six projectors and mechanical shutter. Multiple projector enables to improve the image resolution and brightness as compared with the former EV. Observer can watch the 360 degree panoramic stereo image using liquid crystal shutter glasses.
